The HP StorageWorks Virtual Array 7100 uses virtual array technology to deliver the best availability and manageability of your data, making it an ideal choice for heterogeneous environments. A single StorageWorks VA 7100 delivers extremely high availability: up to 99.95% uptime. If you combine two or more VA 7100s in a mirrored MC/Serviceguard environment, with two or more hosts and two switches, your availability can go even higher.HP's online hot-swappable architecture virtually eliminates planned downtime. HP's virtual array technology lets you create new files or LUNs quickly, without worrying about the underlying physical technology. You can even mix drive sizes or download a firmware upgrade, all without interrupting service. Traditional disk array technology can't do that.
